Patients undergo blood sample collection at baseline and then on days 0, 7, 14, 28, and 56 for safety and immunological studies. Blood samples are analyzed for mycoplasma by PCR; dendritic cell phenotype by flow cytometry; detection of adenovirus CCL21 by nested PCR; and adenoviral antibodies by ELISA. Patients also undergo tissue aspirate or biopsy on days 0 and 7 (during bronchoscopy or CT-guided procedure). Tissue samples are analyzed for immune-modulating cytokines (i.e., IFNγ, CXCL9, and CXCL10) by quantitative RT-PCR; detection of tumor infiltrating leukocytes by immunohistochemistry; CD83+ DC, CXCR3, CCR7, CCL21 and CD3+ T-cells, CD4, and CD8 by flow cytometry; determination of tumor expression of tumor-associated antigen by RT-PCR; and evaluation of immune modulation by ELISPOT assays.
